ECOLOGICAL SAFETY OF THE BLACK SEAECOSYSTEM WHEN CONSTRUCTING ANDMAINTAINING THE GAS MAIN-LINE 'RUSSIA-TURKEY'

摘要

The main pipeline Russia-Turkey is a unique engineering system from the view point ofrnits technical characteristics, being a pioneer in the field of pipe-line construction.rnThe paper considers different types of technogenic impact that may occurred whilernconstructing and running the on-land section of the gas main-line. These effects can endangerrnair and aquatic ecosystems, earth resources and soil, animals and plants, social environment.rnThe paper gives some recommendations to be followed by constructors under differentrnnatural conditions, which ensures optimal ecological control.rnThe construction and maintenance of the gas main-line sea section is to be done at therndepth of 2150 m, which has not been practiced anywhere in the world yet.rnThe paper also presents the results of the studies of the water and sea-bottom sedimentsrnin the area of the supposed main-line track.rnThe results also show that the gas main-line construction is not going to cause anyrnappreciable effect on the Black Sea ecosystem.rnThe ecological and economic assesses of the project are highly positive providing for arncomplex of measures to be prepared and realized on the way of ensuring its total ecologicalrnsafety. The project also takes account of the International Regulations and Acts governing inrnthe region of the supposed construction.
